Hall mobility of cuprous oxide thin films deposited by reactive direct-current magnetron sputtering
Cuprous oxide (Cu[subscript 2]O) is a promising earth-abundant semiconductor for photovoltaic applications. We report Hall mobilities of polycrystalline Cu[subscript 2]O thin films deposited by reactive dc magnetron sputtering. High substrate growth temperature enhances film grain structure and Hall...

description | Cuprous oxide (Cu[subscript 2]O) is a promising earth-abundant semiconductor for photovoltaic applications. We report Hall mobilities of polycrystalline Cu[subscript 2]O thin films deposited by reactive dc magnetron sputtering. High substrate growth temperature enhances film grain structure and Hall mobility. Temperature-dependent Hall mobilities measured on these films are comparable to monocrystalline Cu[subscript 2]O at temperatures above 250 K, reaching 62 cm[superscript 2]/V s at room temperature. At lower temperatures, the Hall mobility appears limited by carrier scattering from ionized centers. These observations indicate that sputtered Cu[subscript 2]O films at high substrate growth temperature may be suitable for thin-film photovoltaic applications. |
